Blizzard hack exposes millions of accounts

Anyone who plays Starcraft, World of Warcraft or Diablo online will likely need to change their passwords soon, as Blizzard (ATVI) on Thursday acknowledged that millions of its users’ Battle.net accounts have been hacked. In a question-and-answer session posted on its official website, Blizzard said that users’ email addresses, secret security question answers, cryptographically-scrambled passwords and other key information was stolen by an unidentified hacker. Blizzard said that it has seen no evidence yet to suggest that this information has been used by the hacker, or that the hacker had shared the information with any third parties. All the same, the company is encouraging its users to change their passwords as soon as possible.
